Royals 6, Twins 4

MINNEAPOLIS — Erik Kratz homered twice after replacing an ailing Salvador Perez, and Jason Vargas pitched seven strong innings to lead the first-place Royals. Vargas had his scoreless innings streak snapped at 17 when Oswaldo Arcia hit a solo homer in the seventh. Perez had two hits and two RBIs before leaving in the seventh because of discomfort in his right knee.
